T 0 cZZ whom it may concern:

Be it known that I, CHARLES LAYTON GRA- HAM, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Shoe Heel, of which the following is a specification.

This invention relates to boots and shoes and more particularly to means for straightening the heels of shoes to effect a perfect balance of the shoe and ankle and to prevent the shoe from running over.

The object of the invention is to provide a simple and efficient device of this character which may be readily applied to either leather or rubber heels and which is adjustable to vary the inclination of the heel to suit different persons.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 represents a side elevation of a shoe heel equipped with this invention.

Fig. 2 is a bottom plan view thereof.

Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2.

Fig. 4 is a bottom plan view of a heel showing a slight-1y different form of the invention; and

Fig. 5 is a transverse section taken on the line 55 of Fig. 4. I

In the embodiment illustrated in Figs. 1 to 3 a shoe heel 1 is shown constructed of leather, rubber or other suitable material having a plate 2 of suitable metal arranged over the inner face thereof and having a plug carrying chamber 3 extending through a portion of the heel 1 at any desired point it being here shown located at the outer edge near one corner of the heel. This chamber 3 is designed to receive and hold an adjustable plug 4 of rubber, metal or composition. This plug 4 is secured within chamber or socket 3 by means of screws 5 twobeing here shown and which are equipped with heads (ihaving swiveled connectionwith the plug. These screws have threaded engagement with the bottom of the socket or ehamher 3 which is preferably thickened'as shown in Fig. 3 so thatwhen the screwsare turned tion to counteract or correct malformation of the foot of the wearer.

The screws 5 are equipped with a locking pin 7 inserted through transversely extending apertures 8 and which holds the screws against turning after they have once been adjusted.

It is to be understood of course that this equalizer plug 4 may be located at any desired point adjacent the periphery of the heel and is designed to elevate the heel at a given point for the purpose above set forth.

In the form shown in Figs. 4 and 5 a wear plate or lift 10 of hard rubber or metal is mounted on the surface engaging face of the heel being spaced therefrom by means of an annular lift 11 to provide a clearance for the heads of the attaching nails 12 which pass through the main lift 14 without friction for a purpose presently to be described. An intermediate or central .support 13 is also arranged between the lifts 10 and 14 and is preferably constructed of the same material as the member 11.

The resilient lift of rubber 15 may be made of different degrees of hardness for cushioning the shock of the heel in walking. A metal plate 16 is embedded in the heel structure 15 and is secured by the nails 12. These nails pass loosely through the plate 14 through a clinching lift of leather 17 and a metal clinching plate 18 to adapt the resilient lift or heel proper 15 to be compressed when pressure is brought upon the heel.

Nails 19 connect the wear plate 10 and have their points embedded and clinched in the leather lift 17 these points being turned down by contact with the clinching plate 18.

The plate 16 has a socket or chamber 3 carried thereby outside the heel 15 and is designed to hold an equalizerplug 4" similar to the plug 4 shown in the other figures and which is designed for the same purpose. This plug 4 is adjustably mounted in the chamber 3 by screws S -similar to those of the other figures and which are heldagainst turning' by a lockingpin 7;

It is of course understood that the plug 4 may be located at any desired point and it is used for the same purpose as the plug l.

Various changes in the form, shape, proportion and other minor details of construction may be made without departing from the principle or sacrificing any of the advantages of the claimed invention.

1 claim The combination with a shoe heel, of a plate secured thereto, a socket carried by said I plate and opening downwardly, a plug mounted in said socket, a screw swiveled in said plug and having threaded engagement with the top of the socket to provide for 1 the projection and retraction of the plug, and means for locking the plug in adjusted position.

In testimony that I claim the foregoing as my own, I have hereto afixed my signature 20 in the presence of two witnesses.
